To determine:
The two or three specialized human tissues that do not have any blood vessels. Determine how these tissues might survive without direct blood supply.
Introduction:
Blood is a connective tissue which flows from heart through arteries and veins to all body. Formed elements and plasma are the two components of blood. The formed elements consist of Red blood cells, white blood cells, and platelets.
Platelets are important in preventing blood loss as they are involved in blood clotting process. Red blood cells consist of a pigment called hemoglobin. It has high affinity towards oxygen. White blood cells lack pigments and so called as White blood cell.
Explanation of Solution
Every living organism requires a regular supply of nutrients and oxygen in the body. These functions are done by circulatory system. Circulatory systems play a major role in transportation of materials inside the body. Substances like, water, nutrients, hormones, and oxygen are transported inside the body by circulatory system.
Most of the cells and tissues of human organ system receives blood supply by cardiovascular system. But there are some tissues that do not receive blood supply. Some example of such tissues is: Epithelial tissue, cornea and cartilage.
As transportation of nutrients and other materials is very important for the normal functioning of organ systems, the question arise that how these tissues that do not receive blood supply functions and gain nutrients. The answer is by the help of surrounding connective tissue the lymphatic fluid.
The lymphatic system is a part of the circulatory system and immune system that have interconnected lymphatic vessels which contain a clear fluid called lymph. Lymphatic system comprises cells, tissues and other organs which defend our body against infections and disease. It is also comprised of the lymph-a clear fluid which is found outside the cells.
The tissues that do not receive blood supply receive nutrients through lymph.

PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen. How would increased estrogen affect the river otter population?

- magine that you are conducting research on fruit type and seed dispersal. You submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document. Describe two characteristics that you would expect in seeds that are dispersed by the wind. Contrast this with what you would expect for seeds that are gathered, buried or eaten by animals, and explain why they are different. (Editor’s note: Providing this information in your discussion will help readers to consider the significance of the research).arrow_forwardWhat is the difference between Uniporters, Symporters and Antiporters?
