Question
Chapter 44.5, Problem 6LO
Summary Introduction
To describe: The structure and function of the human heart are inter-related including the heart’s conduction system.
Introduction: A heart is a hollow and muscular organ which is located under the breastbone in the chest cavity. The main function of the heart is the pumping of blood to various organs of the body. The heart is made up of cardiac muscles and which are attached to the network of collagen fibers.

Include the specific arteries and veins involved in the answer.arrow_forwardBlood is pushed out of the heart through a large vessel, called the aorta. The aorta then divides into smaller and smaller blood vessels, eventually reaching vessels called capillaries. Capillaries are so small that oxygen and nutrients can diffuse across the vessel walls and into the tissues of the body, with CO2 and waste diffusing back into the blood. Let's say that the cross-sectional area of the aorta is 1 cm2 = 100 mm2. The blood pumps through the aorta at 100 mm/s but only through the capillaries at 1 mm/s. If each capillary has a cross-sectional area of 20 mm2, how many capillaries must there be in the body? Note: these numbers are not physiologically correct, but were chosen to make the math easier. The blood velocity through the aorta is closer to 300 mm/s. The capillaries have a total cross-sectional area of ~600,000 mm2 (6000 cm2), with a blood flow rate closer to 0.2 mm/s.arrow_forward
- The Greek anatomist Erasistratus, originally from Ceos, identified the correct function of the right atrioventricular valve of the human heart, which was to prevent backward flow of blood from: the right ventricle to the right atrium the right ventricle to the left ventricle the right ventricle to the left atrium the left ventricle to the right ventriclearrow_forwardDescribe the flow of blood through the heart from where it returns to the heart through where it leaves to travel to body tissues. Make sure to include all appropriate anatomical structures.arrow_forwardHuman blood flows from the aorta to the capillaries. A girl has an aorta radius of 13 mm. ASsume she has 7 billion capillaries in the body, the capillaries radius average 4 µm (micrometer), and the blood speed average 0.5 mm/s in the capillaries. The blood speed is mm/s in the aorta.
