Consider the functions of the kidney in the urinary system and the blood vessels in the circulatory system. what tissue type is
Bess [88]

Connective tissue is the type of tissue common to the blood in the circulatory system and kidneys in the excretory system.

Renal fascia and blood are two different connective tissues found in the excretory system and circulatory system respectively. All the connective tissues have a common origin, known to be mesodermal. Moreover, they connect two different body parts. Blood connects the body organs and the renal fascia in the kidneys connect the kidneys with the adrenal glands.

Functions of renal fascia and blood are as follows:

Renal fascia (alternatively called gerota's capsule or gerota's fascia) is surrounded by two layers of adipose tissue. The primary function of this tissue involves holding up these tissues and providing a firm hold to protect them from any injury caused by unexpected accidents.

Blood is composed of four main components, plasma, platelets, erythrocytes (RBCs), and leukocytes (WBCs). Some of its functions include:

● The primary function of blood is to supply oxygen to the cells, tissues, and organs in the body

● supplying nutrients and minerals to the body's organs

● removing carbon dioxide and other waste materials like lactic acid, and urea.

● helps in regulating body temperature

● helps in the clotting process during the time of any injury through the action of platelets

● helps in fighting against diseases and infection through the action of WBCs.

Why testes is extra abdominal in position in man ?​
denis-greek [22]
Extra-abdominal position means that the testes hang outside the abdomen and are not in it. This is important because the sperms in the testes are very susceptible to high temperatures - meaning that they can easily die due to high temperatures like what we have within the abdomen

How can color blindness be treated
JulijaS [17]

There is currently no treatment for inherited colour blindness. Colour filters or contact lenses can be used in some situations to enhance the brightness between some colours and these are occasionally used in the workplace, but many colour blind people find these actually confuse them further rather than help.
