What is the functional nature of a portal system and how does it differ from normal venous return flow?
A portal system is a special type of blood circulation where blood from one capillary bed flows into a second capillary bed before returning to the heart. The hepatic portal system, for example, carries nutrient-rich blood from the digestive organs to the liver for processing. This differs from normal venous return flow where blood goes directly from capillaries to veins and then back to the heart.
Where does the thoracic duct join the venous system?

What is the network of passageways that carries materials from one part of the cell to another?
Endoplasmic Reticulum
What percentage of the blood is contained in the venous system?
Depending on body size (body surface area) and state of health, the human venous system contains approximately 67-72 percent of the entire blood volume.
Whats venous fluid overload?
Venous fluid overload refers to an increase in the amount of blood volume within the venous system, which can lead to venous congestion. This can occur due to conditions like heart failure, kidney disease, or liver disease, causing symptoms like edema, shortness of breath, and fatigue. Treatment involves addressing the underlying condition and managing fluid intake.
Who carries the digested food through all parts of the body?

What does the venous system do?
The venous system is responsible for returning deoxygenated blood from the tissues back to the heart. It transports this blood through a network of veins, which have valves to prevent the backflow of blood. The venous system also plays a role in regulating blood volume and pressure in the body.

What needed materials does the circulatory system carry to the body cells?

How is digested food carried to your cells?
The digested food is in form of glucose which is broken down in mitochondria to release energy.
What parts of circulatory system that carries digested fats away from intestines?
The lymphatic system is responsible for carrying digested fats away from the intestines. Special vessels called lacteals within the small intestine absorb fats and transport them as chyle to the lymphatic system, which eventually returns the fats to the bloodstream.
Materials to be digested are stored in what organ?
Digestion is a process that begins as soon as the food enters your mouth. The food is not stored anywhere; it moves continually through the digestive system, being digested. There are no pauses.
Is more blood found in the venous system than anywhere else in the cardiovascular system?
Yes, 65-70% of the blood volume is in the venous system.
What carries food materials away from the leaf?
The Phloem. ~ As it is the two way transport system in a leaf.
What organ system transports needed materials to the cells and carries wastes away from cells?
mitochondrion
What is the blood vessel which carries from intestine to the liver?
The liver is the end of the hepatic portal system, which involves a series of veins that stretch from various organs of the gastrointestinal tract. Most of this material is either absorbed water, chyle, or other digested materials, including sugar. The hepatic portal vein is the final vein before these materials from the GI tract enter the liver.
