How does the structure of the capillaries help diffusion occur fast enough to keep you alive?
The structure of capillaries help diffusion occur fast enough to keep you alive by the nutrients and gases occurs in these specialized blood vessels which are between arteries and veins.
What are the blood vessels in which nutrient exchange occurs?
Capillaries. Its one-celled thick structure help it to perform its work efficiently
What structure is microscopic blood vessels that are only one cell in thickness?
capillaries
Which structure is a tiny ball of capillaries?
glomerulus
What is the structure of the capillaries wall?
very thin, often a cell thick
What structure is known as the functional unit of the cardiovascular system?
Capillaries are referred to as the functional unit of the circulatory system.
What is the structure of continuous capillaries best suited to and why?
They are best suited for mammals and they help regulate the permeability of the capillaries. They are mostly found in the hypodermis, lungs, skeletal muscles, heart, nerves, and fat storage cells called adipose tissue.
What structure has the lowest blood pressure in the systemic circulation?
in the capillaries
What structure do RBCs move through single file?
capillaries
The larger lymphatic vessels are most similar in structure to?
capillaries
Which part of nephron is a network of capillaries whose job is to reclaim useful materials from the filtrate?
peritubular capillaries
How does capillaries help them do their job?
Capillaries work in the same way as vessels and veins but they also help by receiving food molecules from the small intestine. And also if a vessel or vein get damaged, they can divert blood away from the injury to reduce blood loss.
