Fat and blood are categorized into which type of tissues?

Fungi obtain their nutirents by what method?
What are pathogens?
Most disease causing infections are fought by which organ system of our body?
Answer:
Fat is categorized as adipose tissue and blood as a fluid connective tissue consisting of the plasma and cells that circulate in the blood vessels. (Source: MGH)Fungi obtain nutrients in three ways: * Saprotrophs break down dead or inert organic matter e.g. leaf litter.
* Parasites exploit living organic matter by living on a host and often leading to disease
* Symbionts form a relationship with another organism where either both benefit or the fungi benefits without causing harm to the other partner.Pathogens are disease-causing organisms, such as bacteria and viruses.The disease causing infections are faught by the lymphoid organs. Lymphoid organs include: * adenoids (two glands located at the back of the nasal passage)
* appendix (a small tube that is connected to the large intestine)
* blood vessels (the arteries, veins, and capillaries through which blood flows)
* bone marrow (the soft, fatty tissue found in bone cavities)
* lymph nodes (small organs shaped like beans, which are located throughout the body and connect via the lymphatic vessels)
* lymphatic vessels (a network of channels throughout the body that carries lymphocytes to the lymphoid organs and bloodstream)
* Peyer's patches (lymphoid tissue in the small intestine)
* spleen (a fist-sized organ located in the abdominal cavity)
* thymus (two lobes that join in front of the trachea behind the breast bone)
* tonsils (two oval masses in the back of the throat)

-fat and blood are cartegorised as connective tissue.
-the algae make their own food through photosynthesis.
-disease causing infections are fought by the immune system which comprises of the WBC's in the blood and complement factors.

Fat and blood are categorized as connective tissue.Fungi obtain their nutrients by absorption."A pathogen...is a biological agent that causes disease or illness to its host."Most disease causing infections are fought by the immune system.
