Explanation:
The arch of aorta is a continuation of ascending aorta and terminates at the intervertebral disc of fourth and fifth thoracic vertebrae. The superior part of the arch of aorta branches off into three major arteries. The first branch of arch of aorta is the largest branch and is known as the brachiocephalic trunk.
The brachiocephalic trunk divides and forms the subclavian artery and right common carotid artery. Right common carotid artery supplied blood to the right side of the head and neck while the right subclavian artery delivers blood to the right upper limb.
Hence, any blood clot in the first branch of arch of aorta, that is the brachiocephalic trunk would affect the blood supply to the right side of the head and neck and right upper arm.
Answer:
A cell is defined as the structural and functional unit of an organism.
The average size of the prokaryotic cell lies between 0.1 to 10 micrometers whereas the average size of the eukaryotic cell is approximately 25 micrometers.
Four things are found in all the cells: genetic material (either DNA or RNA), cell membrane, cytoplasm, and the ribosome.
All the living cells grow and reproduce (sexually or asexually) and have the ability to respond to stimuli.
Thus, characteristics of a cell may include: cell grows and reproduces, responds to stimuli, contains DNA or RNA, not both , and contains a cell membrane.
