What is the correct sequence of structural organization from smallest to largest?
Organ system > organ > tissue > cell
Cell > tissue > organ > organ system
Tissue > organ system > organ > cell
Molecule > cell > organ > tissue
The structural organization in the body begins at the cellular level, followed by tissues, then organs, and finally organ systems. This sequence correctly orders from smallest to largest. Other sequences are out of order.
Which organ is primarily responsible for pumping blood throughout the body?
Heart
Liver
Kidney
Brain
The heart is the central organ that pumps blood through both systemic and pulmonary circulations. Other organs have different roles such as filtration, detoxification, or neural processing.
The sagittal plane divides the body into which sections?
Front and back
Top and bottom
Left and right
Diagonal sections
The sagittal plane runs vertically and divides the body into left and right portions. Frontal (coronal) divides front/back and transverse divides top/bottom. Diagonal sections are described by oblique planes.
The kidneys are a major component of which body system?
Urinary system
Circulatory system
Respiratory system
Nervous system
The kidneys filter blood to remove waste and produce urine, making them integral to the urinary system. They also help regulate fluid and electrolyte balance. They are not primary organs in the other listed systems.
Homeostasis can best be defined as:
Maintaining a stable internal environment
Rapid changes in the external environment
Accumulation of metabolic waste
Unregulated growth of cells
Homeostasis refers to the maintenance of a constant internal environment within physiological limits. It involves regulated processes like temperature or pH control. It is not about rapid external changes or unregulated cell growth.
Which tissue type lines the cavities and surfaces of structures throughout the body?
Epithelial tissue
Connective tissue
Muscle tissue
Nervous tissue
Epithelial tissue forms continuous sheets that cover body surfaces and line cavities or passageways. It provides protection and selective permeability. Other tissue types have different primary functions.
Which organelle is known as the 'powerhouse' of the cell, producing ATP?
Mitochondrion
Ribosome
Golgi apparatus
Endoplasmic reticulum
Mitochondria generate ATP through oxidative phosphorylation, earning them the nickname 'powerhouses.' Ribosomes synthesize proteins, while Golgi and ER have roles in processing and transport.
Which is an example of a negative feedback mechanism in human physiology?
Blood clotting
Childbirth contractions
Regulation of body temperature
Ovulation surge
Negative feedback counteracts deviations from a set point, such as shivering or sweating to regulate temperature. Blood clotting and childbirth use positive feedback, while ovulation involves hormonal surges.
In anatomical directional terms, the nose is ___ to the eyes.
Lateral
Medial
Superior
Distal
Medial refers to closer to the midline of the body, and the nose is nearer to the midline than the eyes. Lateral is farther from the midline, superior is above, and distal refers to farther from an attachment point.
What is the primary function of the alveoli in the respiratory system?
Filter airborne particulates
Exchange gases between air and blood
Produce mucus to trap pathogens
Pump air in and out of the lungs
Alveoli are tiny air sacs where oxygen and carbon dioxide diffuse between air and pulmonary capillaries. They are specialized for gas exchange rather than filtering, mucus production, or mechanical pumping.
Which organ system includes the spleen, thymus, and lymph nodes?
Lymphatic system
Endocrine system
Digestive system
Integumentary system
The lymphatic system consists of lymph nodes, spleen, thymus, and lymphatic vessels, and functions in immune response and fluid balance. Other systems serve hormonal, digestive, or protective roles.
The secretion of insulin by the pancreas in response to high blood glucose is an example of which regulatory mechanism?
Positive feedback
Negative feedback
Feedforward control
Homeostatic overshoot
Insulin release reduces elevated blood glucose, counteracting the initial stimulus, which is characteristic of negative feedback. Positive feedback amplifies change, and feedforward control anticipates changes.
Which type of epithelial tissue is best suited for absorption and secretion?
Simple columnar epithelium
Simple squamous epithelium
Stratified squamous epithelium
Pseudostratified columnar epithelium
Simple columnar epithelium has tall cells with ample cytoplasm, ideal for absorption and secretion in locations like the digestive tract. Simple squamous is best for diffusion, and stratified types protect against abrasion.
Which organ has both endocrine and exocrine functions?
Pancreas
Liver
Thyroid
Kidney
The pancreas secretes digestive enzymes into the duodenum (exocrine) and releases insulin and glucagon into the bloodstream (endocrine). The liver has exocrine-like bile secretion but not conventional endocrine hormones.
What is the function of synovial fluid in a joint?
Provide oxygen to cartilage
Lubricate and reduce friction between articulating surfaces
Produce red blood cells
Transmit nerve impulses across the joint
Synovial fluid is a viscous fluid within joint cavities that lubricates cartilage-covered surfaces to minimize friction during movement. It does not transport oxygen, produce blood cells, or conduct nerve signals.
Which buffering system is most important for maintaining blood pH in humans?
Phosphate buffer system
Bicarbonate buffer system
Protein buffer system
Respiratory buffer system
The bicarbonate buffer system is the primary extracellular buffer in blood, neutralizing excess acids or bases to stabilize pH. Phosphate buffers are more important intracellularly, and proteins contribute but are secondary.
How does the hypothalamus integrate nervous and endocrine responses to regulate homeostasis?
It sends neural signals only to muscles
It releases hormones to the pituitary and processes neural input
It secretes digestive enzymes
It functions independently of the pituitary gland
The hypothalamus receives neural signals and secretes releasing hormones that act on the pituitary gland, linking the nervous and endocrine systems in homeostatic control. It does not secrete digestive enzymes or act in isolation.
In type 1 diabetes mellitus, which failure of feedback regulation leads to persistently high blood glucose?
Excess insulin production
Autoimmune destruction of insulin-producing cells
Continuous glucagon suppression
Overactive negative feedback in the thyroid
Type 1 diabetes involves autoimmune destruction of pancreatic beta cells, eliminating insulin production and failing to lower blood glucose via negative feedback. This contrasts with glucagon or thyroid regulation.
Severe dehydration increases blood osmolarity; which physiological response helps restore fluid balance?
Decreased antidiuretic hormone (ADH) release
Increased ADH release to promote water reabsorption
Increased urine output
Peripheral vasodilation
High blood osmolarity stimulates the release of ADH from the posterior pituitary, leading to increased water reabsorption in the kidneys and reduced urine output. Vasodilation and increased urine output would worsen dehydration.
The renin-angiotensin-aldosterone system (RAAS) exemplifies coordination between which body systems?
Immune and nervous systems
Cardiovascular and urinary systems
Digestive and respiratory systems
Integumentary and skeletal systems
RAAS involves the kidneys (urinary system) releasing renin and the adrenal cortex releasing aldosterone to influence blood pressure and volume (cardiovascular system). It bridges endocrine, renal, and cardiovascular functions.
