Concept explainers
To state: The main function of blood capillaries.
Introduction: The cardiovascular system, which is also known as circulatory system, allows the blood to flow throughout the body and transports nutrients, gases, and other important enzymes in and out of the cells. The cardiovascular system is composed of two components: heart and the blood vessels.
To name: The main ways substances cross the walls of capillaries.

- Name and give the location of the major arteries and veins in the systemic circulation.arrow_forwardExplain the process of ion, blood and fluid exchange in the capillariesarrow_forwardDescribe the three layers that typically form the wall of a blood vessel, and state the function of each.arrow_forward
- Describe two routes by which substances can escape the bloodstream and pass through a capillary wall into the tissue fluid.arrow_forwardExplain how blood flow through tissues is regulated in general and in specific organs.arrow_forwardDescribe the structures and functions of different types of capillaries.arrow_forward
- Describe the mechanisms by which substances enter and leavecapillaries.arrow_forwardMark ALL the statements about capillaries that are TRUE. Select one or more: a. Towards the venule end of the capillary, the blood pressure is higher than the osmotic pressure. b. Fluid will leave the capillaries when the osmotic pressure exceeds the blood pressure. c. Capillaries are only one cell layer thick so the blood moves through them at low velocity. d. Capillaries have a total cross-sectional area that is greater than any other class of vessels. e. The blood pressure will decrease as the blood flows through the capillaries from the arterioles.arrow_forwardDescribe laminar flow and turbulent flow through a tube.What conditions cause turbulent flow of blood?arrow_forward
- Differentiate an artery from a vein. Include a description of the reason why they are different structurally.arrow_forwardDescribe inter-relationship between blood vessel radius, vascular resistance, blood flow, blood pressure and blood flow velocity.arrow_forwardList the percent distribution of blood in the large arteries,small arteries, arterioles, capillaries, small veins, and largeveinsarrow_forward
