Enumerate the function of Cardio-vascular system in animals
Step by step
Solved in 4 steps
- Use this labelled diagram of a human heart & major blood vessels to answer these Which structure is labelled "D"? questions. Aorta Black arrows indicate direction of blood flow Blue structures contain deoxygenated blood Red structures contain oxygenated blood Cardiac muscle Inferior vena cava Left atrium A- B Left ventricle Mitral valve Pulmonary artery Pulmonary valve D- Pulmonary veins Right atrium N- M- Right ventricle F Superior vena cava Tricuspid valve K-Compare function of the double pump system and the circulation pathway of human heart. Include the specific arteries and veins involved in the answer.Hearts are vascular pumps, but the myocardium also needs an oxygen supply. Use a comparative approach to discuss different solutions to this problem in mammals and birds; in teleost fish; and in tunas, salmonid fish, and sharks. Draw the structure of spongy and compact myocardia in relation to their vascular supply.
- Predict what might happen to cardiac muscle tissue in which the intercalated discs were not functional.?Trace the flow of blood through a mammalian heart, naming the four chambers and their valves, and explaining where the blood entering each atrium comes from and where blood leaving each ventricle goes. When the ventricles contract, what prevents blood from reen-tering the atria? What factors cause blood to move forward at high pressure in the aorta?Use this labelled diagram of a human heart & major blood vessels to answer these Which structure is labelled "K"? questions.
