STOMACH: Organ in which a large part of protein digestion takes place with the help of an enzyme called pepsin (Fowler et al.,2023).

SMALL INTESTINE: Part of the digestion where further breakdown of food is assisted by accessory organs such as the pancreas, which is part of the endocrine system ( Fowler et al.,2023).

ARTERIES: Move oxygenated blood away from the heart to the rest of the body.

CAPILLARIES: Connect the circulatory system to the respiratory system, and are sites where nutrients, waste, and oxygen are exchanged (Fowler et al., 2023).

ALVEOLI: The location of oxygen and carbon dioxide exchange connects the respiratory system to the circulatory system (Fowler et al.,2023).

DIAPHRAGM: A muscle responsible for creating a negative pressure around the lungs, allowing them to inflate (Fowler et al.,2023).

PANCREAS: Responsible for assisting digestion and regulating blood glucose levels ( Fowler et al.,2023).

ADRENAL GLANDS: Create epinephrine and norepinephrine, which are responsible for the fight or flight response the human body experiences (Fowler et al.,2023).

JOINTS: There are three types of joints: fibrous, cartilaginous, and synovial, which are responsible for bone connection (Fowler et al.,2023).

CARDIAC MUSCLE: Involuntary muscle responsible for controlling blood pressure, also part of the circulatory system.

NEURONS: Special cells in the nervous system that transmit information through electrical and chemical signals.

THE PERIPHERAL NERVOUS SYSTEM: This is the bridge from the central nervous system to the rest of the body, containing the autonomic and sensory somatic nervous systems (Fowler et al.,2023).

ADAPTIVE IMMUNITY: More specific to a pathogen and can not be mobilized without information from the innate immune deficiency; it also gives the host long-term protection with immune memory (Fowler et al.,2023).

LYMPHOCYTES: White blood cells that can be T or B cells created in bone marrow. Lymphocytes can travel in the circulatory system as well as the lymphatic system (Fowler et al.,2023).

OVARIES: Responsible for the production and development of eggs.

GONADES: Produce hormones that are responsible for human development and reproduction, also part of the endocrine system (Fowler et al.,2023).
