What is the functions of lymphoid tissues?
Lymphoid tissues play a crucial role in the immune system by producing, storing, and activating lymphocytes, which are essential for the body's defense against pathogens. They include primary lymphoid organs like the bone marrow and thymus, where lymphocytes mature, as well as secondary lymphoid organs such as lymph nodes and the spleen, where immune responses are initiated. Additionally, lymphoid tissues help filter and trap pathogens and foreign particles, facilitating their elimination from the body. Overall, they are integral to maintaining immune surveillance and response.
What are baby organs?
Baby organs are the internal organs that form and develop in an infant's body during pregnancy. These organs are essential for performing vital functions such as respiration, digestion, and circulation. The development and proper functioning of baby organs are crucial for the health and well-being of the infant both before and after birth.
What is enternal organs?
Typically, internal organs refer to the organs located inside the body cavities, such as the heart, lungs, liver, and stomach. These organs perform vital functions to maintain the body's health and overall well-being.
How does a female leaf muntjac?
Female leaf muntjacs give birth to a single fawn after a gestation period of about 6-7 months. The newborn fawn is typically well-developed and able to walk within a few hours of birth. The mother hides the fawn in dense vegetation and returns periodically to nurse it.
Could an organism have organs but no tissues. Explain?
No, an organism cannot have organs without tissues. Organs are composed of different types of tissues that work together to perform specific functions. Tissues are groups of cells that are organized structurally and functionally, serving as the building blocks of organs.
All the lymphoid organs are well developed before birth?
no
What are all parts of the lymphatic system?
The lymphatic system can be broadly divided into the conducting system and the lymphoid tissue. The conducting system carries the lymph and consists of tubular vessels that include the lymph capillaries, the lymph vessels, and the right and left thoracic ducts. The lymphoid tissue is primarily involved in immune responses and consists of lymphocytes and other white blood cells enmeshed in connective tissue through which the lymph passes. Regions of the lymphoid tissue that are densely packed with lymphocytes are known as lymphoid follicles. Lymphoid tissue can either be structurally well organized as lymph nodes or may consist of loosely organized lymphoid follicles known as the Mucosa-Associated Lymohoid Tissue (MALT) The central or primary lymphoid organs generate lymphocytes from immature progenitor cells. The Thymus and the Bone Marrow constitute the primary lymphoid tissues involved in the production and early selection of lymphocytes. Secondary or peripheral lymphoid organs maintain mature naive lymphocytes and initiate an adaptive immune response. The peripheral lymphoid organs are the sites of lymphocyte activation by antigen. Activation leads to clonal expansion and affinity maturation. Mature lymphocytes recirculate between the blood and the peripheral lymphoid organs until they encounter their specific antigen. Secondary lymphoid tissue provides the environment for the foreign or altered native molecules (Antigens) to interact with the lymphocytes. It is exemplified by the lymph nodes , and the lymphoid follicles in Tonsils, Peyer's Patches, Spleen, adenoids, Skin, etc. that are associated with the (MALT).
What type of coelom does an enterocoelous animal have?
A coelomate animal is the one which has a body cavity in which well developed organs can be accomodated.
Why do pregnant teens often have difficulty delivering babiess?
Teens are not psychologically prepared to have the baby. The reproductive organs are not well developed before the age 18. So 19 can be an exception to the above statement. Younger teens will face many problems in delivering the babies. The hormone system is not well prepared. The soft organs are not well developed. The bony part is not well developed.All these factors lead to problems in delivering a baby.

What are the characteristics of less-developed countries?
There are a number of characteristics of less developed countries. These include high Birth Rate, low education, as well as poor health.
The Cephalization of the body planes a grasshopper?
Animals can be divided both horizontally and vertically. Grasshopper cephalization means they have heads that are well developed and include sense organs.
Is it organs's or organs'?
The correct way to say it is well-organized or organized well
Are rhinos marsupials?
No. Rhinos are placental mammals meaning they give birth to relatively well developed young. Marsupials give birth to underdeveloped young that are nourished and develop in a pouch.
Is Monaco medc or ledc?
Belgium is more an medc, because it is well economically developed and the birth and death rate are equal
Does the ocelot give birth to live young?
Yes, ocelots give birth to live young. They typically have a litter size of 1-3 kittens, which are born well-developed and ready to move and hunt shortly after birth.
Is the liver of a fetal pig active?
Fetal pigs are relatively large with well-developed organs that are easily visible. As long as the pork industry exists, fetal pigs will be relatively abundant, making them the prime choice for classroom dissections. The development of the lymphatic system and the formation of blood circulation occur at different stages of fetal pig development. The first lymphatic organ to become present is the thymus. Lymphocyte builds up in the spleen on the 70th day. By day 77, the thymus is already completely developed and is distinguishable from other organs. Also, follicles are present on the tongue and intestines on day 77. On the 84th day, periarteriolar lymphoid sheaths appear in the fetal pig. By this time, the liver and bone marrow are active and functional.
