Anatomy and Physiology for Health and Social Care
R/600/8956 BTEC Nationals 10

Guided learning hours: 60
Aim and purpose
This unit aims to enable learners to understand aspects of the anatomy and physiology of human body systems. Learners will be able to gain an overview of the organisation of the human body before looking at how body systems work together to provide energy for the body. Learners will have the opportunity to investigate how homeostatic mechanisms operate in the body.

Unit introduction
This unit introduces core knowledge of cellular structure and function, and the organisation of the body as a whole, and then builds on this to develop a more detailed knowledge of the fine anatomy and physiology of the systems involved in energy metabolism. Learners will examine the homeostatic mechanisms involved in regulating these systems to maintain health. Learners will be given the opportunity to undertake practical activities which will require them to take measurements of the cardio-vascular system, the respiratory system and of body temperature, using noninvasive techniques to investigate normal responses to routine variations in body functioning. This unit provides the core understanding of human physiology that underpins the study of the specialist physiology units within this programme. The unit also provides an overview of body functioning that is valuable for anyone working or intending to work in a field relating to health and social care.

Learning outcomes
On completion of this unit a learner should:

1 2 3 4

Know the organisation of the human body Understand the functioning of the body systems associated with energy metabolism Understand how homeostatic mechanisms operate in the maintenance of an internal environment Be able to interpret data obtained from monitoring routine activities with reference to the functioning of healthy body systems.

Unit content
1 Know the organisation of the human body
Organisation: cells; tissues; organs; systems Cells: cell membrane, nucleus, cytoplasm; organelles – mitochondria, endoplasmic reticulum (smooth and rough), Golgi apparatus, lysosome Tissues: ◊ ◊ ◊ ◊ ◊

epithelial: simple (cuboidal, columnar, squamous, ciliated), compound (simple, keratinised) connective: blood, cartilage, bone, areolar, adipose muscle: striated, non-striated, cardiac nervous: neurones, neoroglia examples of where each tissue type might be found

Body organs: location of heart, lungs, brain, stomach, liver, pancreas, duodenum, ileum, colon, kidneys, bladder, ovaries/testes, uterus; structure and function of the skin Systems: gross structure of cardiovascular, respiratory, digestive, renal, nervous, endocrine, reproductive, lymphatic, musculo-skeletal, immune Main functions of systems: overall function of each system, eg digestion of food materials, maintenance of oxygen supply, transport and supply of materials to cells, receptors of information from the environment, co-ordination, eliminating waste products, reproduction; overview of interactions of the different structures within each system

2 Understand the functioning of the body systems associated with energy metabolism Energy: forms, eg chemical, heat, sound, electrical, light Energy laws: conservation of energy; transformation of energy Energy metabolism: role of energy in the body; anabolism and catabolism; activities involved in supplying energy to the cells of the body– roles of cardiovascular, respiratory and digestive systems Cardiovascular system: heart – structure, cardiac cycle, heart rate, stroke volume, blood pressure, blood vessels– arteries, arterioles, capillaries, venules, veins; pulmonary and systemic circulation; structure and function of the blood Respiratory system: role of air passages in nose; structure and functions of...
