Blood NU1303- Sciences 1 Captioning Statement Video and audio content at the University uses closed captions generated by automatic speech recognition (ASR). The ASR process is based on machine learning algorithms which automatically transcribe voice to text. According to our technology providers this process is approximately 70-90% accurate depending on the quality of the audio, and consequently video and audio closed captions may include some transcription errors. It is therefore important to recognise that the original recording is the most accurate reflection of the content, and not the captions. If you require accurate captions as part of your reasonable adjustments, please contact the Inclusion Centre to discuss your requirements 26/04/24 2 Blood This topic relates to: Learning outcome(s) Gain an understanding of what blood is; Identify the key components which make up blood; Identify the roles of the main components in the blood.

Blood Volume and Composition Plasma is a mixture of water, amino acids, proteins, carbohydrates, lipids, vitamins, hormones, electrolytes, and cellular wastes The percentage of formed elements in the blood is normally 45%, and is mainly red blood cells; this percentage is called the hematocrit (HCT) Plasma makes up 55% of the blood volume White blood cells and platelets make up
