Biology 1 Rat Practical Review - Labeled with Functions
Right atrium: Receives deoxygenated blood from body via vena cavae.
Right ventricle: Pumps deoxygenated blood to lungs via pulmonary arteries.
Left atrium: Receives oxygenated blood from lungs via pulmonary veins. -
Left ventricle: Pumps oxygenated blood to body via aorta.
Vena cavae: Bring deoxygenated blood to right atrium. -
Pulmonary arteries: Carry deoxygenated blood to lungs. -
Pulmonary veins: Return oxygenated blood to left atrium. -
Aorta: Distributes oxygenated blood to body. -
Atrioventricular valves: Tricuspid (right) and bicuspid/mitral (left). -
Semilunar valves: Pulmonary and aortic. -
Right side: Deoxygenated blood. -
Left side: Oxygenated blood. -
Thickest myocardium: Left ventricle, due to pumping blood to body.
Trachea: - Cartilage rings prevent collapse. -
Lungs: - Gas exchange occurs in alveoli. -
Brain - monitors CO2 levels to regulate breathing.
Diaphragm: - Contracts: Increases chest volume, inhaling air. -
Relaxes: Decreases chest volume, exhaling air
- Liver: - Function: Metabolism, detoxification, bile production. -
Secretion: Bile, emulsifies fats. -
Stomach: - Valves: Cardiac (esophagus) and pyloric (duodenum). -
Secretion: Gastric juice, aids digestion. -
Esophagus: - Muscle contractions Peristalsis, Substance: Bolus.
Duodenum: -Function: Receives bile and pancreatic enzymes, Begins small intestine.
Kidney: Filtration, waste removal, fluid balance. -
Functional unit: Nephron. - Tubes: Ureters carry waste to bladder. -
Bladder: : Urethra leads away.
Spleen: - Function: Filters blood, stores white blood cells.
- Thymus: - Produces T cells for immune system. -
Pancreas: - Digestive secretion: Enzymes for nutrient breakdown. - Endocrine secretion: Insulin and glucagon. -
Adrenal gland: - Produces adrenaline.
Vas deferens: - Transports sperm. -
Seminal vesicles: - Secretes seminal fluid. -
Testes: - Produces sperm; located in scrotum. -
Uterus: - Tube: Fallopian tubes transport egg.
- Lens: Focuses light. -
Cornea: Protects. -
Sclera: Supports. -
Cerebrum: Higher brain functions. -
Tissue: Meninges.
- Cerebellum: Coordination. -
Medulla: Vital functions regulation.
