Why does it take tendons and ligaments longer to heal than many bone injuries? 7. Blood is a fluid connective tissue. Justify. (plz saare bata do.)

Answer 1

Explanation:

Ans1) Animals in colder regions have thick layers of fat, because fat acts as an insulator and doesn't allow their body to escape heat , which helps them survive in such extreme temperature.

It store food which help them ,when there is shortage of food.

Ans2) Ligaments

• • they connect to bone .
• •they contain very little martix
• •the tissue is very elastic with good strength

tendons

1. They connect bone to muscle
2. they contain more martix as compared to ligament .
3. this tissue has great strength but limited flexibility.

Ans 3 ka d

Ans 4

@ Connective Tissues (may be)

b) Adipose tissue

Ans 5 ???

Ans 6

Tendons attach muscles to bones. Tendons generally have a more limited blood supply than muscles.

Ligaments stabilize and support the body's joints.

Ans 7

Blood is a fluid connective tissues as it has fluid martix. This is fluid martix is called Plasma. Due to which blood is called fluid connective tissues.
