Answer:
The correct answer is- Immune system
Explanation:
There are physical, chemical and immunological barriers present in our body which helps us to protect from the foreign antigen. They all assist each other and helps in pathogen removal from our body.
The physical barrier includes skin, gastrointestinal tract, respiratory tract, etc which do not allow the microbe to enter the body. Chemical barriers include tear, saliva, acid in the stomach which kills microbes on the body surface.
Immune cells like macrophages, B cells kills microbes when it gets in the body. Lymphatic system also contain immune cells and helps in microbe removal.
So the immune system is assisted by physical barrier, chemical barrier, and lymphatic system.
Answer:
Peroxisomes
Explanation:
Peroxisomes are the membrane-bound organelles present in eukaryotic cells only. These are specifically abundant in liver cells and are involved in the breakdown of fatty acids. Peroxisomes have enzymes that catalyze metabolic reactions in which hydrogen from various compounds is transferred to oxygen. These reactions produce hydrogen peroxide. Catalase is the enzyme present in peroxisomes that rapidly splits excess hydrogen peroxide to water and oxygen, rendering it harmless.
