Answer:
There are three main types of blood vessels:
1)Artery ---
i) It is a blood vessel having a thick wall.
ii) It carries blood from the heart to different parts of the body.
iii) On regulatory demand of the body it can dilate or constrict.
iv) It doesn't contain any valve.
v) All arteries carry oxygenated blood except the pulmonary artery.
2)Vein ---
i) It is a blood vessel having a thin wall.
ii) It brings blood from different parts to the heart.
iii) It can't dilate or constrict under normal conditions.
iv) It contains valves that allow the blood to flow in one direction towards the heart.
v) All veins carry deoxygenated blood except the pulmonary vein.
3)Capillary ---
i) It is a very narrow blood vessel that has very thin walls.
ii) It forms a network throughout the body in all living cells connecting arteries to veins.
iii) It can dilate or constrict according to the requirement of tissue.
iv) It doesn't have any valve.
v) It contains mixed blood as it connects arteries and veins
The humerus-
A long bone of the upper forelimb. It articulates proximally with the scapula to form the soulder joint and distally with the radius and ulna to form the elbow joint.
<span>Proximally the humerus has a rounded projection known as the head. </span>
Cranially at the lateral aspect of the head is a large prominence- the greater tubercle. The lesser tubercle lies medially. Both tubercles act as a sight for muscle attachment. At the distal end of the humerus is a condyle which articulates with the radius & ulna & forms part of the elbow.
The diaphysis of the humerus is twisted.
<span>In the dog a supra condylar foramen is present- a large hole in the condyle.

The Femur-This is the thigh bone and is the largest bone in the body, it is a long bone and is similar in structure to the humerus in that it has a head, neck, shaft & lateral & medial condyles. The femoral head articulates with the acetabulum proximally to form the hip joint, lateral to the head is the greater trochanter and on the medialTh side is a lesser trochanter (for muscle attachment). At the distal end of the femur are 2 condyles that articulate with the tibia to form the stifle joint. Between the 2 condyles is the trochlear groove along which the patella can move.
Here is some information. Hope this helps ☺
Answer:
1) 5 kingdom system of classification is a type of classification in which all the living organisms are classified into 5 kingdoms i. e. protista, monera, fungi, plantae and animalia.
2) Plants are autotrophic organisms while animals are heterotrophic. Plants have cell wall while cell wall is absent in animal. Plants are fixed while animals move from place to place.
3) Both plants and animals are made of cell. Both plants and animals are multicellular organisms. Both plants and animals reproduce.
4) Plants make their own food while fungi are unable to make their own food. Plant cell wall is made of cellulose while fungi cell wall is made of chitin.
A glucose molecule is a monomer of starch and cellulose
Answer:
D
Explanation:
The changes in eating noted in the first study are due to fibers that are passing through the lateral hypothalamus. The lateral hypothalamus is a region of the brain with a key function of coordinating an array of cognitive and physical processes such as feeding
