Compare and contrast the structure and function of the lymphatic and circulatory system. how are they different? how are they similar? include the general functions of each. make sure you include the structure of the vessels that carry the fluid in each system and the of the lymphatic fluid and blood.

All circulatory and lymphatic

systems are vascular networks that

bear fluid connective tissue

The discrepancies will be

addressed in the section below.

Explanation:

Circulatory system is a network of blood vessels through which blood is pumped by a rhythmically beating muscular device, called heart.

There is no such pumping device in lymphatic system, there are lymphatic vessels and lymph nodes.

The artery divides into

arterioles and forms a capillary network within tissues,

while the capillaries

rejoin as veins and form a

vein later.

Therefore, circulation in

the cardiovascular system is

possible.

On one side, the lymph capillaries are

closed, i.e. at the point of origin,

but they form larger lymph vessels together.

So the lymph does not

circulate, but only drains into the

veins.

Blood helps in transportation of nutrients, hormones, etc but most importantly it transports respiratory gases: specially oxygen- with the help of hemoglobin present in RBC .

RBCs are not at all present in lymph, but lots of WBCs are present: hence lymph nodes are the areas where WBCs can fight with germs. Fat absorption and transportation is done by lymphatic system .

i believe the correct answer is the virus gets an envelope that contains host molecules when it leaves the host cell.

explanation:

during the bidding/release stage of a virus, it encapsulates itself with part of the membrane of the host cells in this case the cells of the monkey and is the reason as to why the scientist found the genetic material of the monkey on the viral cell surface.

further explanation

to understand this answer, we have to know the cycle a virus undergoes to replicate. a virus is basically a bunch of genetic material enclosed in a capsule and lacks any machinery or organelles to ensure their survival so they must enter a host cell in order to get the environment needed to survive. some viruses enter and lyse(destroy) the host cell after they have replicated and undergo the lytic cycle while some enter and leave the cell intact after replicating and these undergo a lysogenic cycle. to enter the cell, they undergo the first process called attachment by binding to specific receptors and co-receptors on the surface of the host cell. after attaching to the cell, they start the second phase called penetration where virus enters or is engulfed whole by the host cell through a process called endocytosis. it is the same process that a cell takes up materials it needs or pathogens around it. uncoating of the virus then happens after the virus has been engulfed and is the third stage. the virus then undergoes releasing of its genetic material in the host's matrix.   the materials then enter the nucleus and undergo biosynthesis by adding themselves in strands of rna being translated and then copies of the virus are produced in addition to the host genetic material. the material/newly formed viral material then undergoes assembly inside the host cell and form a capsule around them. the virus undergoes the last release/budding stage by binding to the host membrane and pushing outwards. in doing so when they tear away from the host membrane, they pick up the genetic material from the membrane of the host cell to form their envelope.
